Met Office Global Ocean Model with 3D and 2D Daily Forecast Fields

A 2-year rolling archive of the Global Ocean component of the Met Office's operational coupled forecast system. The dataset provides 3D daily mean fields of temperature, salinity, and velocities, plus 2D daily fields for sea ice and surface properties, generated from deterministic forecasts with lead times out to 7 days. It is produced by the UK Met Office and interpolated onto a regular latitude-longitude grid.

Use Cases

• Analyzing global ocean temperature and salinity patterns based on the 3D daily mean fields
• Forecasting sea ice movement and thickness based on the 2D daily mean sea ice velocity and fraction fields
• Modeling surface ocean currents based on the hourly instantaneous fields for surface currents
• Studying mixed layer depth variability based on the 2D daily mean field

Strengths

• Provides a coupled physical analysis from an operational forecasting system running since May 2022
• Includes multiple data types: 3D daily fields, 2D daily fields, and instantaneous hourly fields
• Forecast products are generated once daily with lead times out to 7 days

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Last update date is unknown; freshness unverified
